Maven 打包常用插件介绍

一、Maven 生成Jar，提示 没有主清单属性

1. 使用maven-shade-plugin插件

在pom.xml添加代码：

<build>
        <finalName>App</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>1.2.1</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                        <configuration>
                            <transformers>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                    <mainClass>这里填完整入口类名</mainClass>
                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
</build>

2. 使用maven-jar-plugin插件

这个不能解决maven引用的库也打包到目标jar里

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-jar-plugin</artifactId>
	<version>2.3.1</version>
	<configuration>
		<archive>
			<manifest>
				<addClasspath>true</addClasspath>
			</manifest>
			<manifestEntries>
				<Main-Class>
					主类名称
				</Main-Class>
			</manifestEntries>
		</archive>
	</configuration>
</plugin>

二、sprintboot打包

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.0.1.RELEASE</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

打包命令：

mvn package spring-boot:repackage

三、资源文件拷贝到指定位置

			<plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <version>3.1.0</version>
                <executions>
                    <execution>
                        <id>copy-resources</id>
                        <phase>validate</phase>
                        <goals>
                            <goal>copy-resources</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${project.build.directory}</outputDirectory>
                            <resources>
                                <resource>
                                    <directory>src/main/resources</directory>
                                    <filtering>true</filtering>
                                </resource>
                            </resources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

四、spring boot 资源文件

		<resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <filtering>true</filtering>
				 <!-- <excludes>
                    <exclude>*.properties</exclude>
                    <exclude>*.xml</exclude>
					<exclude>*.db</exclude>
                </excludes> -->
            </resource>
            <resource>
                <directory>src/main/webapp</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
